It's been at least 10 years since I tore a teeny strip off the top of my nail. I don't remember how I did it, but it was about 1mm wide and went from the tip of the nail to the cuticle. Every time it grew, the little nick was there so it would catch and tear again. No amount of buffing or filing helped. I'm not sure how, but eventually it grew so thay only one side of the ridge tore. So now it's like this (pic attached). I've been keeping it really short and well filed and buffed and I thought I had it finally sorted, but no, it lifted again yesterday and now I'm back to square 1. It's not sore but it catches on everything and is going to tear if I don't cut it right down again (this is the longest it's been in years). Over the years I've tried super glue, various home gel varnishes, some sort of wrap that a nail technician put on it and nothing has worked. Does anyone here have a Christmas miracle for me?
